Railroad permanent way construction



Patented July 14, 1931 ADAM RAMRAUHER, or MUNI'CH, GERMANY RAILROAD PERMANENT WAYV CoNsTRUcTioN Application med March 1s, 1929, serial No. 3147.997, andj in'eermany March 22, 192s.v 'i

A cross-sleeper railroad track of wood and concrete, the wooden ties being carried in concrete where they meet the rails', is known. The cross-sleepers run transversely 'IL over the track in its entire width, conveyingdisturbances from one side of the track to the other, if not in so high a degree as cross-ties generally. In addition, the concrete beds break, as experience has shown,

l atea length of 7() cm.

The principal aim of the present invention is to avoid these disadvantages. It is furthermore intended to attain connec-V V tion between the individual parts which is u as safe as possible, elastic, which protects vehicles and rails in the bestV way, simple andv easy to providev and to take apart again. At the same time, however, an effortless regulation of the rail-level should be had destructive ellect on `the ballasting material.

In railroad permanent way ofwood andl concrete, the concrete supports are, for this purpose, each formed of two concrete blocks, arranged with a suitable gap which is bridged over by the wooden sleep which is connected with the blocks and the tie-plate in a dismountable manner. The jaws of the tie-plate which hold the rail are raised, and the holding-clips, carried in niches in the jaws and serving to fasten the rail in position, are extended to the exterior, so that the supporting metal or boards, to be laid under the rails in order to compensate for the difference in level in the road, as well as the rails themselves are held laterally at any level of the jaws.

The invention is illustratively exemplified in the accompanying drawings, in which, Figure l is a substantially transverse sectional View of a road bed; Figure 2 is a plan view of a section of the road bed; Figure 3 is a transverse sectional view,v

of a rail and tie plate; and Figure 4 is a top plan View of the tie plate.

Referring to the drawings and particularly Figures l and 2, each concrete support consists of two concrete blocks a and a', spaced apart a suitable distance and bridged over by a wooden tie b of about without employing a tamping pick, with its UNITED STATES PATENT' 'ori-legi 5 6 cm. in thickness.r The concreteblocks 2,500 sq. cm., thus being able to carry theV heaviestwheel pressure, providing that the roadbed of the track is made suliciently firm, which is ensured by previous rolling or ramming Y' f v. The concrete blocks are furnished with a groove holding al prominence a2 .in the center, *for the reception of .thejwoiodenl tie I). rThe tieb is provided witlrnotches corresponding to these prominences a2, so that longitudinal'. displacement of the vtie fis impossible.V The latter, as may'beseen from. Figs. l, and 2,'proje'cts :laterally over thetwo concrete blocks a and a 'suliciently :to enable it to ybe carried by theworkmen.

I It has exactly the same-width as. the tie plate c, so that :it 'is completely covered by the latter, in order' toy prevent the formationfof water deposits. 2 i The'connection.V between the tie-plate, the

woodenl tie'` and the concrete blocks a and a 4ismade by means of screw-bolts d, which engage nuts d. VThe latter are let` into the concrete blocks afan'd eafrom' beneath andy are enclosed suitably in felt so as to protect the concrete. 1

vThe so formed bridge nowV carries the running rail e between two highly-curved jaws c ofthe tie-plate c. Both footlbolts fon the interior and the exterior fix'the running rail c by means of in the usual way (Fig. 3).

The latter, however, are, vas maybe seen from Figs. 3 and 4, embedded in niches in the jaws c and extended exteriorly far enough to enableA the level of the running rail e to be regulated in a high degree by theinsertion of one or more supporting metal shim plates or boardsw to be ylaid between the jawsc. In this way it is made possible Vfor even the slightest sinking in a' supporting bridge to be compensated lfor Without anything further. The high jaws c and long holding-clips .g are especially useful in allowing the running rail to be regulated asy to its level, such regulation being effected holding-clips g by using of a longer foot-screw, of approximately 3 cm., so that adjustment of the elevation ofthe supporting bridge itself would not be necessary only after some years of 5 wear. f

The holding of the track to the gauge is efected by means of cast iron ymembers JL, which are suitably positioned yas shown in Figure l and fastened with four screws It and clip-plates h2 to the feet of thevrails e. Where wooden ties as-described abovecannot be used, e. g. on account of the ravages of ants, the correspondinglymoulded'con-` crete blocks are bridged over with iron supe ports, which are provided with soft covering,

liningjthe points of contact.

ci Claims for patent.

1. In a railway track structure,`the com.- bination with a pair .of rails, of separate n. pairs of concrete blocks arranged along said track, thegblocks of each pair being spaced apart transversely of a rail, a wood tie piece spanning each pair of blocks, and a tie plate separably attached to each pairv otblocks, the wood tie and to therail -to support the latter on the tie above the space between the blocks of a pair. i i f 2. A railway track structure, as claimed in claim 1, in which the tie piateis provided with pairs of' spaced upstanding lugs embracing oppositesides of the rail base, and clamping members adjustable between the pairs of lugs against the base of the rail at one end and avainst the -tie plate beyond the 3l lugs, at the other. end.

3. A railway track structure, as claimed in claim 1, in which the tie plate is provided with pairs of spaced i upstanding lugs on opposite sides of the rail base, clamping 0- members having arched ends disposed beey tween the pairs of lugs and'disposed againstA the base of ther-ail, the opposite ends of the members being straight and disposed against the tie )late beyond the lugs, shim plates between tie rail and tie plate and means projecting upwardly7 betwcenthe lugs of each pairand Vthrough the clamping` member to clamp the latter against the rail' base, shim plates and tie plate. -v

so 4, In a railway track structure in which the rail is adjustably supported upon its tie plateathe combination therewith of separate pairs of concrete blocks arrangedalong said tracks, the 'biocks of each pair being spaced apart transversely of a rail., a wood tie piece spanning each `pair l of blocks, and a tie piate separably attached to each pair of blocks.y the wood tie and to the rail to. support `thelatter on the tie above the -space between the blocks of a pair. c'
